need help with validating a 9-digit number.

555555555
666666666
777777777
888888888
999999999
4-5 position(s) CANNOT BE 00 --
123001234
6-9 position(s) CANNOT BE 00 --
234550000
The nine numbers CANNOT BE sequential -- but only the following 4 four below, for the time being --
012345678
123456789
987654321
098765432
I had just managed to get the first piece done --
"^(?:(?!0+|1+|2+|3+|4+))\d{9}$"
Thanks a TON for the help friends.
